-------------------------------------

             Summary: HYBRID ORC split strategy can generate inconsistent splits across two
otherwise identical runs
                 Key: HIVE-12624
                 URL: https://issues.apache.org/jira/browse/HIVE-12624
             Project: Hive
          Issue Type: Bug
            Reporter: Siddharth Seth


When using the HYBRID strategy to execute the same query twice - the raw splits generated
in the two runs can differ. Wondering if this has something to do with footer caching.
